SPECIFICATION forming part of Letters Patent No. 388,822, datedSeptember 4, 1888.

Application filed April 27, 1397.

To all whom it may concern.-

..le it known that I, \VARREN BUNDY, a citizen of the United States,resident at MinnesotaUity, in the county of \Vinona and State ofMinnesota, have invented certain new and useful Improvements inOrosscut-Saws; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which itappertains to make and use the same, referencebeing had to the accompanying drawings, and to letters or figures ofreference marked thereon,whieh form a part of this specification.

Figure 1 of the drawings is a representation of this invention and is aView of a crosscutsaw. Fig. 2 is a portion of a saw and shows a largerview of the teeth.

This invention has relation to crosscut'saws; and it refers particularlyto the novel forma tion and combination of the teeth, as hereinafter setforth.

In the accompanying drawings, the letter A designates the blade, and B OD the teeth thereof, separated by the intervals E F G, in the ordershown. The teeth 0 O and D l') are cutting-teeth arranged in pairs, OD,as shown, the teeth O being set to the right and D to the left. B Bare ehiseltceth, one such tooth following each pair of cutters, asshown. The teeth are inclined downward and forward from the body of theblade at an angle of about thirty degrees from the transverse verticalline of the blade. The teeth 0 and D are similar, except that one isbeveled away on the left of its cutting-edge, while the tooth D isbeveled away on the right. The teeth are formed with parallel front andrear edges extending from the blade and bounding the intervals E F G, asshown. Each cutting-tooth O l) is formed with a short front edge, h, anda long rear edge, k, and with the oblique front cutting-edge, Z,extending from the end of the short edge to that of the long edge, theangle of the euttingedge Zbeing about thirty degrees from the verticaland its length about equal to that of the short edge h. These teeth (Jl) shear the sides of the cut and are followed by the chisel-shapedcleaner B,which is formed with its front edge, m, extending farther fromthe blade than its rear edge, a, the bottom of the tooth being inclinedat a low angle from a line in the length of the blade and having noRenewed February 27, 1888.

side bevel, its dress being square, so that it presents a transversecutting front at 2, adapted to clear the cut of chip and dust 5 formedby the action of the preceding cuttingteeth D C. These teeth follow eachother at distances which are equal, or nearly so, and the intervals E FG are therefore of about the same width.

As usually constructed it is preferred to throw the front 2 of thecleancntooth B vertically below the inner end of the longer edge of thepreceding tooth C, as shown. For double saws the teeth on one half theblade 6 are formed to point toward the handle of that side, and on theother half toward the handle of the other side.

This saw is designed to do work with comparatively little power. It isreadily filed on account of the formation of the tooth, only one toothbeing filed at a time. The saw is designed to be used for an indefinitelength of time, because as the teeth are worn away by work and filingthe parallel formation of the edges of the intervals between them allowssaid intervals to be extended into the blade. This is especiallyimportant in crosscutsaws having drag or chisel teeth, as these teethrun out after usual filings, making it necessary to So out ofi' all theoldteeth and cut in new ones at a great waste of the blade and greatexpense.

In my saw as the teeth are tiled away they can be lengthened into theblade.

As this saw has only a single drag-tooth, '05 there is nothing behind itto prevent the saw from going right into the work, while in double drag-tooth saws the saw does not hug or cut so readily on account of therunner behind.

Having described this invention, what I claim, and desire to secure byLetters Patent,

A erosseut-saw having the parallel edge aeuteangle cutting-teeth O I)and the parallel edge chisel-form teeth I having the transversecutting-front z, and shorter than the cutting teeth, substantially asspecified.

In testimony whereof I have affixed my signature in presence of twowitnesses.
